Now, the governor from the losing state will have to travel to the winning team's city and sing "The Star Spangled Banner" during a basketball game between the Philadelphia 76ers and Boston Celtics.

There's one little twist: Only Romney will be breaking into song should his New England Patriots fall to the Philadelphia Eagles on Feb. 6.

Rendell has recruited his wife, federal Judge Midge Rendell, a trained opera singer, to fulfill the wager if the Patriots win.

Rendell, who's well-known for his large appetite, says Romney "is a little thinner" than he is — "and he's a little bit more health-conscious," too.

The two states' congressmen were also in a betting mood.

Rep. Bob Brady (search), D-Pa., will wear a Patriots helmet for a week if New England wins; Rep. Marty Meehan (search), D-Mass., will wear an Eagles helmet for a week if the Pats lose, the Philadelphia Daily News reported.

"I've already got a Jevon Kearse helmet ready," Brady told the News.

Brady also made a bet with Maine Gov. John Baldacci (search), who is apparently less calorie-phobic than his Massachusetts counterpart.

"If I win, he sends me L.L. Bean boots [size 11] and a dozen lobsters," Brady told the News. "If he wins, I send him a dozen cheesesteaks, five dozen pretzels, a box of Tastykakes and a Melrose cheesecake."
